VALVE MECHANISM FOR GAS-GOMIRESSORS.

Specification of Letters Patent.

Patented June 29, 1915.

Applicationfiled June 24, 1912. Serial No. 705,645.

To all whom it may. concern:

Be it known that-we, HENRY WV. lawns and HOWARD H. LANNING, citizens of the United States, and residents of Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Valve Mechanism for Gras- Compressors, ofwhich the following is a description, reference being had to the accompanying drawings, which form a part of our specification.

Our invention relates to gas compressing machines, and more particularly to a .machine adapted to be used for compressing pure oxygen.

The object of our invention is the provision of a machine which will be simple and at the same time eificient and durable and so constructed that all of its parts will be readily accessible for inspection or repairs; whereby pure oxygen can be safely compressed to any desired pressure.

Inthe drawings Figure 1 is a front ele vation of our improved machine. Fig. 2 is a side elevation thereof with a portion of the mechanism shown in section. Fig. 3 is a top plan view with the intake and outlet pipes in section and the lower portion of the base, fiy wheel and pulley omitted. Fig. 4 is a sectional. view taken on the line 4A; of Fig. 3, looking in the direction of thearrows. Fig. 5 is a sectional view taken on the line 55 of Fig. 3, looking in the direction of the arrows. Fig. 6 is a cross sectional view taken on the line 6-6 of Fig. 5, looking in the direction of the arrows. Fig. 7 is a detail view in perspective and partially in section of one of the valve cages.

In the specific exemplification of our in vention, the intakeand dischargevalves, illustrated in the drawings, are preferably of the puppet typeand are fitted into removable cages which are suitablygmounted within the housings 34 and 35 formed integral with the cylinder 21. As the compressor or cylinder illustrated is of the double acting type, two inlet and two discharge valves are employed; the cylinder being of course provided with the proper inlet and outlet ports orchannels as hereinafter set forth. The lower part of housings 34 and 35 receive the inlet valve cages 45, 45. These cages are made inthe form of cups with the upper edge of the walls or rims beveled so as to provide suitable valve seats for the inlet valves 46, see Fig. 7. The outside face of the upper portion of the cages 45, 45, are screw threaded so that the cages may be screwed into the threaded openings in the partitions 47 of the housings 34 and 35, see

Figs. 4 and 5; while the remainder of the cages fit snugly into the holes formed in the partitionsor walls 48 of housings 34 and 35; the walls 47 and 48 being separated from each other, as more clearly shown in Figs. 4 and 5, to provide the intake ports 49 which communicate with each other by means of the passages 50, see Fig. 5. Valve cages 45, 45, are preferably provided with the annularflanges51which are adapted to bear against the lower outside surface of housings 34 and 35, as clearly shown in Figs. 4 and 5,.and in order to insure a tight joint, a gasket may be interposed between the flanges and the lower outer surface of the cages and thus prevent any leakage of gas. In order to facilitate the proper securing or removal of the cages 45, and permit of the use of a wrench, the outer extended portion 52 of the cages may be made hexagonal as illustrated in F ig. 7. The side walls of cages 45 are provided with a series of radially extending holes 53 so located that when the cages are properly screwed into place, the holes 53 will register with the intake ports 49 and thus provide communication between ports 49 and the interior of cages 45 below the seat of the valves 46.

The bottom of the intake valve cage 45 is preferably provided with a tappet hole as more clearly shown in Fig. 7 at 54 into which is screwed a short pipe 55, see Fig. 4. This pipe 55 projects downwardly through the lower flange 21 of the lower cylinder head and terminates in a pet cook 56. As the valve cages 45 are identical and might be interchanged, the hole in the bottom of inlet valve cage 45 seated in housing 34 is closed by a suitable screw plug as shown at 57 so as to prevent the gas escaping there through. The purpose in providing the lower cage with the pipe and pet cock, is to enable the removal of any liquid that may condense or otherwise collect in the lower cage 45, which cage is the lowest point in the intake passages of the cylinder.

The valves 46 are provided with a surface ground to conform with the seats of the cages 45 so that the gas cannot pass about the valves when they are seated. The lower faces of valves 46 are provided with wings or guiding members 58, the edges or side surfaces whereof are machined so as to provide a free working fit within the cup shaped cavity or interior of valve cages the wings or guiding members 58 properly control or guide the movements of the valves to their seats. The upper surfaces of the valves 46 are provided with the bosses or projections 59 which are so arrangedthat they will strike against the adjacent surface or lower end of the discharge valve cages arranged immediately above, and thus limit the lift of the intake valves 46 from their seats.

The upper portions of housings 34 and35 are provided with suitable openings to re ceive the discharge valve cages 60. The inner ends of cages 60, like the inner ends of cages 45, have externally threaded portions which fit into the threaded portions or walls 61, see Figs. 4 and 5; whilethe remainder or plain portion of cages 60 fit snugly into the holes formed in walls 62 of housings 34 and 35; the walls 61 and 62 being separated so as to provide the discharge ports 63; which ports communicate with the discharge passage 64, see Fig. 5. The valve cages 60, like the valve cages 45, are preferably provided with annular flanges as shown at 65, which bear upon the upper or outlet walls of housings 34 and 35. if desired, a suitable gasket may be placed intermediate of the annular flanges 65 and the walls of the housings so as to insure gas tight connection. provided with a series of radially extending holes 66 which are adapted to register with the discharge-ports 63 when the valve cages 60 have been properly screwed into place, thus providing communication between discharge ports 63 and the interior of cages 60 above discharge valves 67. The valve cages 60 may be provided with hexagonal portions 63 in order to facilitate the use of a wrench for inserting or removing the cages.

The discharge valve cages 60 are open at both ends as clearly shown in Figs. 4 and-5,

with theopenings in the lower ends thereof beveled and properly formed so as to provide seats within the cages 60 for the discharge valves 67 which are mounted so as to move inwardly; the valves 67 normally closing the openings in the lower ends of the cages 60. The openings in the upper ends of cages 60 are preferably threaded internally to receive the threaded ends of plugs 69; the plugs 69 being provided with flanges 69 which bear on the outer upper edges of cages 60 and form tight joints, thus preventing the gas from escaping through the openings in the upper ends of the cages. The large openings in the upper ends of the cages are for the purpose of permitting the valves 67 to be inserted into the cages. These plugs may be provided with hexagonal or other suitable portions or sur- The side walls of cages 60 are faces so as to facilitate the use of a wrench when it is desired to insert or remove the plugs. The discharge valves 67 are provided with suitable, guiding portions or wings '70 on the upper faces of the valves; the edges of the wings or guide portions being machined to a suitable diameter so as to permit the valves to work freely within the cages 60. The upper intersecting surfaces of the wings 70 are preferably provided with a projection or button as shown at-71, see Fig. 6, which is providedwith a; slot adapted to receive a screw driver or similar implement thus providing'meansfor grinding the valves 67 tofconformity with their seats; at'thesame timethe projections or buttons 71 will act asa meansfor limiting the maximum lift of the discharge valves 67, because the projections 71 will strike against the lower side of plugs 69 when the desired 'maximum lift has been attained bythe valves 67. V I

Intermediate of the walls or partitions47 and 61, in both housings 34 and 35, a gas passage orport 49 is provided. These ports 49 communicate with bothends of cylinder v21, asmore'clearly shown in Fig. 4, and

permit of communication being established between the cylinder and inlet ports 49'and discharge or outlet ports 63, when the respective inlet and-discharge valves are operated. I I

The conduit or pipe 72 constitutes the intake pipe leading from the gasometer, or other suitable source of supply; and this pipe is preferably screwed into the opening. in wall 47 of housing 34, thus conveying gas into the upper port or chamber 49 which latter communicates with lower chamber or port 49 by meansof the passage-50. The discharge chambers or'ports 63, which are connected by discharge passage 64, permit the discharge of compressed gas to flow into discharge pipe 73 which connects with the upper wall on partition 62 of housing 34.,

The operation of our improved invention is as follows:Power is'applied to impart reciprocating motion to piston '29 inside of cylinder 21. As the piston 29 travels al-; ternately f-romend to end within cylinder 21, it draws in the gas throughintake pipe 72 which latter'communicates with port 49 allowing the gas to flow into the port and gas passage 50 communicating with port 4-9 at the lower end of the cylinder. Assuming the pistonin' the positionshown in Fig. 4, its downwardstroke will indu'cethe gas to lift intake valve 46 in housing 34 and allow thepiston will'also compress the gas in the upper part of the cylinder and drive it back through port 49* in housing 34, lifting discharge valve 67 and allow the compressed gas to enter port 63 which communicates with discharge pipe 7 3. It is of course understood that the continued reciprocation of the piston will act in like manner on the gas in the lower portion of the cylinder 21, as previously described, compressing the gas, forcing it into port 49 thereby lifting discharge valve 67 located in housing 35, permitting the gas to enter port 63, which communicates with chamber or passage 64 having communication at its upper end with discharge pipe 7 3.

We have shown and described what we believe to be the best form of our invention, but the same may be modified in certain de tails without, however, departing from the spirit of our invention, and we do not wish, therefore, to be understood as limiting. ourselves to the exact construction shown and described, but i hat we claim and wish to secure by Letters Patent, is 1- 1.
